RGS13

Regulator of G-protein signaling 13 is a protein that in humans is encoded by the RGS13 gene.[1][2]

RGS 13 is a member of R4 subfamily of RGS (Regulators of G Protein Signaling) proteins which have only short peptide sequences flanking the RGS domain. RGS 13 suppresses the immunoglobulin E– mediated allergic responses.[3]

The protein encoded by this gene is a member of the regulator of G protein signaling (RGS) family. RGS family members share similarity with S. cerevisiae SST2 and C. elegans egl-10 proteins, which contain a characteristic conserved RGS domain. RGS proteins accelerate GTPase activity of G protein alpha-subunits, thereby driving G protein into their inactive GDP-bound form, thus negatively regulating G protein signaling. RGS proteins have been implicated in the fine tuning of a variety of cellular events in response to G protein-coupled receptor activation. The biological function of this gene, however, is unknown. Two transcript variants encoding the same isoform exist.[2]
